473: partial chains certificate validation feature. Already validated
474: non-inheriting CA certificates are now marked as trusted roots. This
475: way it can be ensured that a leaf's delegated resources are properly
476: covered, and at the same time most validation paths are
477: significantly shortened.
478: <li>Support for gzip and deflate HTTP Content-Encoding compression was

480: saving around 50% of bandwidth.
481: <li>ASPA support was updated to draft-ietf-sidrops-aspa-profile-16.
482: As part of supporting AFI-agnostic ASPAs, the JSON syntax for
483: Validated ASPA Payloads changed in both filemode and normal output.
484: <li>In filemode (-f option) the applicable manifests are now shown as
485: part of the signature path.
486: <li>A new -P option was added to manually specify a moment in time
487: to use when parsing the validity window of certificates. Useful
488: for regression testing. Default is invocation time of rpki-client.
489: <li>The -A option will now also exclude ASPA data from the JSON output.
490: <li>The synchronisation protocol used to sync the repository is now
491: included in the OpenMetrics output.
492: <li>Improved accounting by tracking objects both by repo and tal.
493: <li>Check whether products listed on a manifest were issued by the same
494: authority as the manifest itself.
495: <li>File modification timestamps of objects retrieved via RRDP are now
496: deterministically set to prepare the on-disk cache for seamless
497: failovers from RRDP to RSYNC.
498: <li>Improved detection of RRDP session desynchronization: a check was
499: added to compare whether the delta hashes associated to previously
500: seen serials are different in newly fetched notification files.
501: <li>Improved handling of RRDP deltas in which objects are published,
502: withdrawn, and published again.
503: <li>Disallow X.509 v2 issuer and subject unique identifiers in certs.
504: RPKI CAs will never issue certificates with V2 unique identifiers.
505: <li>A check to disallow duplicate X.509 certificate extensions was
506: added.
507: <li>A check to disallow empty sets of IP Addresses or AS numbers in RFC
508: 3779 extensions was added.

510: Object is missing.
511: <li>Warnings about unrecoverable message digest mismatches now include
512: the manifestNumber to aid debugging the cause.
513: <li>A check was added to disallow multiple RRDP publish elements for the
514: same file in RRDP snapshots. If this error condition is encountered,
515: the RRDP transfer is failed and the RP falls back to rsync.
516: <li>A compliance check for the proper X.509 Certificate version and CRL
517: version was added.
518: <li>A compliance check was added to ensure CMS Signed Objects contain
519: SignedData, in accordance to RFC 6488 section 3 checklist item 1a.
520: <li>Compliance checks were added for the version, KeyUsage, and
521: ExtendedKeyUsage of EE certificates in Manifest, TAK, and GBR Signed
522: Objects.

748: subsystem commands and arguments. This may change behaviour for exotic
749: configurations, but the most common subsystem configuration
750: (sftp-server) is unlikely to be affected.
1.13 dtucker 751: <li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>:
752: PKCS#11 modules must now be specified by their full
753: paths. Previously dlopen(3) could search for them in system
754: library directories.
1.1 deraadt 755: </ul>
1.12 dtucker 756: <li>New features
1.1 deraadt 757: <ul>
1.12 dtucker 758: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
759: add keystroke timing obfuscation to the client. This attempts
760: to hide inter-keystroke timings by sending interactive traffic at
761: fixed intervals (default: every 20ms) when there is only a small
762: amount of data being sent. It also sends fake "chaff" keystrokes for
763: a random interval after the last real keystroke. These are
764: controlled by a new ssh_config ObscureKeystrokeTiming keyword.
765: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
766: <a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
767: Introduce a transport-level ping facility. This adds
768: a pair of SSH transport protocol messages SSH2_MSG_PING/PONG to
769: implement a ping capability. These messages use numbers in the "local
770: extensions" number space and are advertised using a "ping@openssh.com"
771: ext-info message with a string version number of "0".
1.13 dtucker 772: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
773: allow override of Subsystem directives in sshd Match blocks.
774: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
775: allow forwarding Unix Domain sockets via ssh -W.
776: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
777: add support for configuration tags to ssh(1).
778: This adds a ssh_config(5) "Tag" directive and corresponding
779: "Match tag" predicate that may be used to select blocks of
780: configuration similar to the pf.conf(5) keywords of the same
781: name.
782: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
783: add a "match localnetwork" predicate. This allows matching
784: on the addresses of available network interfaces and may be used to
785: vary the effective client configuration based on network location.
786: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
787: <a href="https://man.openbsd.org/sshd.8">sshd(8)</a>,
788: <a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
789: infrastructure support for KRL
790: extensions. This defines wire formats for optional KRL extensions
791: and implements parsing of the new submessages. No actual extensions
792: are supported at this point.
793: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
794: AuthorizedPrincipalsCommand and AuthorizedKeysCommand now
795: accept two additional %-expansion sequences: %D which expands to
796: the routing domain of the connected session and %C which expands
797: to the addresses and port numbers for the source and destination
798: of the connection.
799: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
800: increase the default work factor (rounds) for the
801: bcrypt KDF used to derive symmetric encryption keys for passphrase
802: protected key files by 50%.
1.1 deraadt 803: </ul>
804: <li>Bugfixes
805: <ul>
1.12 dtucker 806: <li><a href="https://man.openbsd.org/scp.1">scp(1)</a>:
807: fix scp in SFTP mode recursive upload and download of
808: directories that contain symlinks to other directories. In scp mode,
809: the links would be followed, but in SFTP mode they were not.
810: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
811: handle cr+lf (instead of just cr) line endings in
812: sshsig signature files.
813: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
814: interactive mode for ControlPersist sessions if they
815: originally requested a tty.
816: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
817: make PerSourceMaxStartups first-match-wins
818: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
819: limit artificial login delay to a reasonable maximum (5s)
820: and don't delay at all for the "none" authentication mechanism.
1.13 dtucker 821: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
822: Log errors in kex_exchange_identification() with level
1.12 dtucker 823: verbose instead of error to reduce preauth log spam. All of those
824: get logged with a more generic error message by sshpkt_fatal().
825: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
826: correct math for ClientAliveInterval that caused the probes
827: to be sent less frequently than configured.
1.13 dtucker 828: <li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>:
829: improve isolation between loaded PKCS#11 modules
830: by running separate ssh-pkcs11-helpers for each loaded provider.
831: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
832: make -f (fork after authentication) work correctly with
833: multiplexed connections, including ControlPersist.
834: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
835: make ConnectTimeout apply to multiplexing sockets and not
836: just to network connections.
837: <li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>,
838: <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
839: improve defences against invalid PKCS#11
840: modules being loaded by checking that the requested module
841: contains the required symbol before loading it.
842: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
843: fix AuthorizedPrincipalsCommand when AuthorizedKeysCommand
844: appears before it in sshd_config. Since OpenSSH 8.7 the
845: AuthorizedPrincipalsCommand directive was incorrectly ignored in
846: this situation.
847: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>,
848: <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
849: <a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
1.16 jsg 850: remove vestigial support for KRL
1.13 dtucker 851: signatures When the KRL format was originally defined, it included
852: support for signing of KRL objects. However, the code to sign KRLs
1.16 jsg 853: and verify KRL signatures was never completed in OpenSSH. This
1.13 dtucker 854: release removes the partially-implemented code to verify KRLs.
855: All OpenSSH tools now ignore KRL_SECTION_SIGNATURE sections in
856: KRL files.
857: <li>All: fix a number of memory leaks and unreachable/harmless integer
858: overflows.
859: <li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>,
860: <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
861: don't truncate strings logged from PKCS#11 modules
862: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>,
863: <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
864: better validate CASignatureAlgorithms in
865: ssh_config and sshd_config. Previously this directive would accept
866: certificate algorithm names, but these were unusable in practice as
867: OpenSSH does not support CA chains.
868: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
869: make <code>ssh -Q CASignatureAlgorithms</code> only list signature
870: algorithms that are valid for CA signing. Previous behaviour was
871: to list all signing algorithms, including certificate algorithms.
872: <li><a href="https://man.openbsd.org/ssh-keyscan.1">ssh-keyscan(1)</a>:
873: gracefully handle systems where rlimits or the
874: maximum number of open files is larger than INT_MAX
875: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
876: fix "no comment" not showing on when running
877: <code>ssh-keygen -l</code> on multiple keys where one has a comment
878: and other following keys do not.
879: <li><a href="https://man.openbsd.org/scp.1">scp(1)</a>,
1.14 dtucker 880: <a href="https://man.openbsd.org/sftp.1">sftp(1)</a>:
1.13 dtucker 881: adjust ftruncate() logic to handle servers that
882: reorder requests. Previously, if the server reordered requests then
883: the resultant file would be erroneously truncated.
884: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
885: don't incorrectly disable hostname canonicalization when
1.16 jsg 886: CanonicalizeHostname=yes and ProxyJump was explicitly set to
1.13 dtucker 887: "none".
888: <li><a href="https://man.openbsd.org/scp.1">scp(1)</a>:
889: when copying local to remote, check that the source file

1183: <h3>Notes about the source code</h3>
1184: <p>
1185: <code>src.tar.gz</code> contains a source archive starting at <code>/usr/src</code>.
1186: This file contains everything you need except for the kernel sources,
1187: which are in a separate archive.
1188: To extract:
1189: <blockquote><pre>
1190: # <kbd>mkdir -p /usr/src</kbd>
1191: # <kbd>cd /usr/src</kbd>
1192: # <kbd>tar xvfz /tmp/src.tar.gz</kbd>
1193: </pre></blockquote>
1194: <p>
1195: <code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
1196: This file contains all the kernel sources you need to rebuild kernels.
1197: To extract:
1198: <blockquote><pre>
1199: # <kbd>mkdir -p /usr/src/sys</kbd>
1200: # <kbd>cd /usr/src</kbd>
1201: # <kbd>tar xvfz /tmp/sys.tar.gz</kbd>
1202: </pre></blockquote>
1203: <p>
1204: Both of these trees are a regular CVS checkout. Using these trees it
1205: is possible to get a head-start on using the anoncvs servers as
1206: described <a href="anoncvs.html">here</a>.
1207: Using these files
1208: results in a much faster initial CVS update than you could expect from
1209: a fresh checkout of the full OpenBSD source tree.

1218: <blockquote><pre>
1219: # <kbd>cd /usr</kbd>
1220: # <kbd>tar xvfz /tmp/ports.tar.gz</kbd>
1221: </pre></blockquote>
1222: <p>
1223: Go read the <a href="faq/ports/index.html">ports</a> page
1224: if you know nothing about ports
1225: at this point. This text is not a manual of how to use ports.
1226: Rather, it is a set of notes meant to kickstart the user on the
1227: OpenBSD ports system.
1228: <p>
1229: The <i>ports/</i> directory represents a CVS checkout of our ports.
1230: As with our complete source tree, our ports tree is available via
1231: <a href="anoncvs.html">AnonCVS</a>.
1232: So, in order to keep up to date with the -stable branch, you must make
1233: the <i>ports/</i> tree available on a read-write medium and update the tree
1234: with a command like:
1235: <blockquote><pre>
1236: # <kbd>cd /usr/ports</kbd>
1.2 jsg 1237: # <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_7_4</kbd>
1.1 deraadt 1238: </pre></blockquote>
1239: <p>
1240: [Of course, you must replace the server name here with a nearby anoncvs
1241: server.]
1242: <p>
1243: Note that most ports are available as packages on our mirrors. Updated
1244: ports for the 7.4 release will be made available if problems arise.
1245: <p>
1246: If you're interested in seeing a port added, would like to help out, or just
1247: would like to know more, the mailing list
1248: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
